However, it should be understood that these descriptions are only for further illustrating the features and advantages of the present invention, rather than limiting the claims of the present invention.

[0041] The embodiment of the present invention provides a connector, comprising a plug 1 and a socket 2. Figure 1 Shows the state of the two parts when plugged together. Figure 2 The two parts are shown in a state when they are separated. The plug 1 includes a plug housing 14, in which a first plug core 10 is arranged. The plug housing 14 is provided with a wire inlet 15. The socket 2 includes a socket body 21, and a snap wrench 22 is provided on both sides of the socket body 21. The plug housing 14 is provided with a convex column 16 and a convex plate 17 adapted to the snap wrench 22. The convex column 16 is used to clamp the snap wrench 22 during insertion, so that the insertion is more tight and reliable. Figure 3 As shown, the protruding plate 17 is used for separating and disconnecting the plug 1 and the socket 2. With the rotating shaft of the snap wrench 22 as a fulcrum, one corner of the snap wrench 22 presses against the protruding plate 17, and the lever is used to make the separation operation more labor-saving.

[0042] It should be noted that, in the present embodiment, the first ferrule and the second ferrule are respectively arranged in the plug / socket. In other embodiments, the first ferrule and the second ferrule may also be respectively arranged in the socket / plug. The specific arrangement may be based on actual needs, and the present embodiment does not constitute any limitation to this.

[0043] Figure 5 and Figure 6 An example of the first plug core 10 is shown, with one end facing the socket 2 being the plug-in end 3 and the other end being the wiring end 4 for connecting an external wire. Figure 5 This is the view from terminal 4. Figure 6 It is a view from the plug end 3. In this example, one end of the first ferrule 10 is provided with two rows of fixed plug-in parts 50 along the long axis direction of the ferrule body, and the module installation cavity 31 is provided between the two rows of fixed plug-in parts 50, and the other end of the first ferrule 10 is provided with six independent installation cavities 41 along the long axis direction of the ferrule body. It should be noted that the above is only an example of the first ferrule 10. In other examples, the first ferrule 10 can adopt other combination arrangements, and the number of fixed plug-in parts, independent pin sockets and modular plug-in parts configured therein can be set according to actual needs, and this example does not impose any restrictions on them.

[0044] The first plug core 10 supports three wiring modes. The first is the traditional fixed wiring mode, which is realized by the fixed plug-in part 50 in the figure, which is located on both sides of the first modular plug-in part 30 in the figure, and is arranged in two rows parallel to the long side direction of the first plug core 10, and each row can connect ten wires. One end of the fixed plug-in part 50 corresponding to the socket 2 is the plug-in terminal 3c, and the other end is the wiring terminal 4c. The first type of pin 18 of the fixed plug-in part 50 is embedded in the fixed plug-in part 50 along the direction from the wiring terminal 4c to the plug-in terminal 3c, and a screw mounting part 45c corresponding to the wiring terminal is provided on the side.

[0045] The second wiring method is as follows Figure 7 As shown, one or more independent pin sockets 40 are configured as needed and installed in an independent installation cavity 41.

[0046] like Figure 7 and Fig.11 As shown, a snap-in cavity 42 is provided on the inner side of the independent mounting cavity 41 on the independent pin socket 40, and a snap-in mechanism for fixing the independent pin socket 40 to the independent mounting cavity 41 is provided in the snap-in cavity 42. The snap-in mechanism includes a snap-in block 43 and an elastic spring 44. The elastic spring 44 is used to snap-in and limit the independent pin socket 40 after the independent pin socket 40 is inserted into the independent mounting cavity 41 and reaches a preset position. The snap-in block 43 is used to apply a force to the elastic spring 44 under the action of an external force to release the snap-in and limit position on the independent mounting cavity 41. The purpose of setting the snap-in mechanism is to facilitate the loading and unloading of the independent pin socket 40 without the use of additional tools. When installing, just press down to automatically snap-in and limit. When disassembling, press the snap-in block 43 again to release the snap-in and limit position. This structure is compact and ingenious, and the operation is also very convenient.

The installation and removal of the first modular plug-in part 30 can be achieved through the fastening mounting part 35b.

[0049] Fig. 9 is a schematic diagram of a socket 2, the core part of the socket 2 is a second plug core 20, and a plurality of second type plug pins 28 are arranged on the second plug core 20, and the positions of the second type plug pins 28 are adapted to the first type plug pins 18 of the plug. Fig.10 As shown, corresponding to the first modular plug-in portion 30 of the plug 1, the corresponding part on the socket core 20 is also assembled together and can be detached, that is, the second modular plug-in portion 29. The second modular plug-in portion 29 corresponds to the plug-in end 3d at one end of the plug 1 and the wiring end 4d at the other end. The plug-in end 3d has a rectangular tooth-like cross section; and fastening mounting portions 35d are provided at both ends of the second type pins 20 in the arrangement direction.

[0050] like Figure 4 As shown, a first plug core 10 is installed in the plug housing 14, and a wiring cavity is left between the wiring terminal 4 and the plug housing 14, which can be used to accommodate external wires. A detachable slide cover 7 is provided at the position of the cavity of the plug housing 14. The slide cover 7 can be slid open along the slideway 8 to facilitate the connection of wires or the installation of the first modular plug-in part 30; or it can be closed along the slideway 8, and after closing, it can be fixed with a fastener at the position of the slide cover fastening hole 9. In other embodiments, the above-mentioned slide cover part can also be detachably installed on the housing body using other structures or fixing components, which is not specifically limited here.
